Equation: x^2 +2kx +10x +k^2 +5 = 0
Using the discriminant: (2k +10)^2 -4*1*(k^2 +5) = 0
Solving the discriminant: k = -2
4 and the two equal roots are 2/5 and 2/5
If: 6x^2 +2x +k = 0 has equal roots Then using the discriminant of b^2 -4ab=0: 4 -24k=0 => k=-4/-24 => k=1/6 Therefore the value of k = 1/6

That depends on what the value of x is.
It is an expression and a term that are of equal value
4 and the two equal roots are 2/5 and 2/5
Using the discriminant of b^2 -4ac = 0 the value of k works out as -2
If: 6x^2 +2x +k = 0 has equal roots Then using the discriminant of b^2 -4ab=0: 4 -24k=0 => k=-4/-24 => k=1/6 Therefore the value of k = 1/6

That depends on what the value of x is.
It is an expression and a term that are of equal value
Using the discriminant formula for a quadratic equation k has a value of 8/25 or maybe 0.
The solutions are: s = -3/2 and s = -3/2 they have equal roots
you need to know the x or y value
No real roots
Using the discriminant the possible values of k are -9 or 9
The roots are: x = -5 and x = -9
